The summary does not mention AI, ML, or any related terms, nor does it describe any features or performance metrics typically associated with AI/ML-powered devices.
No.
The device is described as an "imaging tool in the evaluation of human tissue microstructure" and generates "two dimensional, cross sectional, real-time depth visualization," indicating a diagnostic rather than therapeutic purpose.
Yes
The device is described as an "imaging tool in the evaluation of human tissue microstructure," which implies its use in diagnosing or aiding in the diagnosis of conditions by providing visual information about tissue.
No
The device description explicitly states it is comprised of a "LuminScan™ Imaging System Console and LuminScan™ Disposable Imaging Kit," indicating the presence of hardware components beyond just software.
Based on the provided information, the LuminScan(TM) Imaging System is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "as an imaging tool in the evaluation of human tissue microstructure by providing two dimensional, cross sectional, real-time depth visualization." This describes a device used in vivo (within the living body) to visualize tissue structure.
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, tissue samples) outside the body to provide information for diagnosis, monitoring, or screening.
- Imaging Modality: Optical Coherence Tomography (OCT) is an imaging technique used to visualize structures within living tissue.
- Anatomical Site: The device is used on "human tissue microstructure" and specifically tested on the "Esophagus" in animal testing, indicating direct application to the body.
The description clearly points to a device used for in vivo imaging, which falls outside the definition of an In Vitro Diagnostic.

Bench Testing:
- Software Verification and Validation Testing: Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for the LuminScan™ Imaging System was considered as a "Minor" level of concern, since failures or latent design flaws in the software are unlikely to cause any injury to the patient or operator.
- Disposable Imaging Kit Testing: The following in-vitro performance tests were completed on the Disposable Imaging Kit; all the tests were found to be within their test acceptance criteria (passing test result): Balloon Diameter, Balloon length, Balloon Burst Testing, Balloon Fatigue Testing, Balloon Inflation/Deflation Testing, Tensile Strength, Endoscopic Compatibility Testing, Airtightness, Retraction testing, Sterilization and Shelf Life Testing, Biocompatibility Testing.
- Reliability Testing: Device reliability was evaluated against several environments factors (e.g., temperature, humidity) when the product was in operation or was properly stored. In additional, vibration testing was performed to evaluate the device reliability when the product was power off. Both tests yielded passing results.
- System Performance Testing: High-level product design requirements of the LuminScan™ Imaging System were evaluated in system performance testing. System performance yielded a passing test result.
Animal Testing:
- Species: Bama miniature pig (Sus scrofa domesticus)
- Quantity: 2
- Sex: One male and one female
- Age: 8-9 months
- Weight: 35-40 kg
- Imaging Anatomical Area: Esophagus

510(k) Number: K112770
Product Name: Nvision VLE Imaging System (OCT)
5. Device Description
LuminScan™ Imaging System is a general imaging system comprised of LuminScan™ Imaging System Console and LuminScan™ Disposable Imaging Kit.
6. Indications for Use
LuminScan™ Imaging System is indicated for use as an imaging tool in the evaluation of human tissue microstructure by providing two dimensional, cross sectional, real-time depth visualization.
7. Clinical Test Conclusion
This section is not applicable because there is not including any clinical performance data with this 510(k) Submission.
8. Comparison of Technological Characteristics
LuminScan™ Imaging System is an optical coherence tomography (OCT) imaging device, which has similar technological characteristics as the predicate device cleared under 510(k) K112770 of NinePoint Medical Inc. Both devices use the principles of swept source OCT to generate high-resolution, two-dimensional, cross-sectional images of tissue microstructures in real time.
The main technological differences between the proposed device and the predicate device are the inflation method of accessory and the parameters of the accessory. The proposed device use automatic pump to inflate balloon of accessory, and controlled by system software. The predicate device use manual method to inflate balloon. In additional, the diameter of the inflation balloon in the proposed device is 16 mm whereas the diameter in the predicated device is 25 mm. Moreover, the inflated pressure of the inflation balloon in the proposed device is 3 atm whereas the pressure in the predicate device is 0.34 atm. Furthermore, the accessory in the proposed device can pass through the endoscopic channel as small as 2.8 mm. The predicate device

requires an endoscopic channel of no less than 3.7 mm.
With risk mitigation mechanisms in the proposed device, however, these differences
between the proposed device and the predicate device in the technological
characteristics are minor and would not raise any questions of safety or effectiveness.

10. Substantially Equivalent (SE) Conclusion
Third Party safety testing, adherence to U.S. FDA design control guidance and ISO 14971, as well as thorough in-house, non-clinical (bench) testing and software validation provide reasonable assurance that the LuminScan™ Imaging System is safe and effective, and is, with respect to intended use and technological characteristics, substantially equivalent to the predicate device, the Nvsion VLE Imaging System under K112770.
